Hello, I know this is an old post but have a question that relates. Is the DATE_AND_TIME variable returned by SFC1 the same as what is shown on the module time? Mine are different. How do I sync them? ------------------------------------------------------------------------------------------ |

Hello Tyhoon; How have you extracted the different bytes from SFB1, and how did you transfer them to the DB registers you show in your VAT table? The DT byte values you show do not match with expected Date_and_Time byte values. See for example what should be the contents of these bytes , in the screenshot below. I suggest you take a few minutes and examine the code instructions presented in the following document to extract the SFB1 CDT to a DB structure (the addressing here is symbolic only). How can you read out the date and time with SFC1 (READ_CLK) and set them with SFC0 (SET_CLK)? https://support.industry.siemens.com/cs/ww/en/view/21222026 Hope this helps, Daniel Chartier |
